MODE OF OPERATING PISTONS 0F PUMPS.

Specification of Letters Patent No. 19,276, dated February 2, 18158.

To all whom t may concern.'

Be it known that I, SIMEoN VooD, of the city and county of Vorcester andState of Massachusetts, have inventeda new and useful Improvement in theMode of Operating the Pistons of Pumps; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being had to the annexed drawing,forming part of this specification, in which- Figure l is an elevationof the apparatus. Fig. 2 is a vertical section taken through axis ofdischarge pipe. Fig. 3 is a horin zontal section on line an. Fig. 4 is avertical section on line y y. Fig. 5 is a view showing operating wheels,taken on a smaller scale than the other figures.

Similar characters of reference in the several figures denote the samepart.

The nature of my invention consists in effecting the operation of thepistons of a system of pumps communicating with a. receiver, by therotation of wheels over the heads of the piston rods, when said rotationis produced by the turning of a horizontal, weighted disk resting uponthe aforesaid wheels; the details of construction and 0peration being asfollows.

In the drawing R is the receiver, communicating with the pumps P P, andhaving a discharge pipe p. The pumps have pistons a, whose rods b riseabove a stationary Hoor f, and have on their extremities, inclinedplanes c. Resting upon the floor f is a system of wheels W W WV,connected by axles a with a central plate d capable of moving around thedischarge pipe p. Upon the wheels aforesaid rests a weighted disk D,connected by a band B with a pulley O, on a shaft E, so that powerapplied to pulley O will turn the disk D about the discharge pipe p.

The piston rods b, have arms z' which rest upon the levers Z, vibratingon their attachment to the supports fm of the floor The operation of theapparatus is as follows Power applied to pulley C rotates disk D, whichby its weight causes the rotation of the wheels W W W, and theconsequent turning of the system about the discharge pipe 29. As thewheels rotate, they encounter the inclined planes c on the piston rods,depressing the pistons. rPhe connection of levers Z and arms z' causesthe depression of one piston to lift the piston in advance. In thismanner a rapid reciprocation of the several pistons obtained, causingwater to be drawn through the several pipes t, and to be forced from thedischarge pipe. Q'

Disclaiming the actuatlng of pistons by the rolling of wheels overupward projecting inclined planes, separately considered, as notembracing the full scope of my invention, what I claim and desire tosecure by Letters Patent, is-

The combination of the weighted disk D, with the system of wheels W WIV, the ioor f and the protruding inclined planes or their equivalent,`arranged and operating substantially as hereinbefore set forth.

In testimony whereof, I have hereunto signed my name before twosubscribing witnesses.
